I appreciate Mr. Pérez-Maldonado´s note in regard to my article on the forwarding agents in Mexico. A stronger illustration would have helped identify the marking he has. In any event, I own an 1867 stampless folded letter (fig. 1) showing the forwarder's name, "Branch Schoenfeld y Ca./Monterey" in blue (37 x 18 mm.), not "Branch Schoenfeld y Ca.", as it was erroneously described by both of us.
Please note that Monterrey is spelled out "MONTEREY", with a single "R". The postmark on my cover is the double circle undated, scarcer than the dated one. It is a "Sello Negro" with "2" (reales) rate marking on the reverse side. It will help if size and color of the marking are reported.
The cover shown in fig. 2 is addressed to "Haugh y Co.", not "Haugk". These changes have been taken care of for an update on the Mexico forwarders.
